As; disclosed in the acconripanying' drawings T' denotes a trackwayextendingin a direction toward the material M to be loaded and traveling on the trackway T is the supporting truck S.

As herein embodied the supportingtruck S comprises the side sills l connected at their; opposite ends by the transversely disposed plates Mounted upon the plates 2 is'the arcuate trackway A extending transversely of the truck S and extending a predetermined distance therebeyond. The trackway A'c'om prises a plurality'of rails 3detachably con? nected as at4-and the rails'at the opposite ends of the trackway are connected by the i any inequalities in-the. ground or other-sur- .versel disposedaxle'lO having fixed to'its brace bars 5. Loosely disposed through each end portion of the bars 5 is the vertically disposed shank '6 having at its lower end the fork 7 affording a mounting for the ground engaging wheel 8. The shank 6 is normally held againstemovementindependentl of the bar 5 by the clamping screw 9 at readed through "the, bar 5- and c0 acting with the shank "6 in a, conventional. manner. The shank 6 together .with the'wheels 8 serve as supports for the, outer portions of the track- -way T and thevertical adjustment of ,the shank 6 readily. permit-s compensation for face with which the whe 1 8'eng g Rotatably supported'by the side sills -1 adjacent the rear endthereof is a transopposite end portions the :flanged wheels 11 ridingu pon the trackway A. The forward end portion lof'eafch of the sills 1 is provided in its lower marginalportion with an, open recess 12 in which is slidably mountedi for vertical movement abearing block 14. As

maintainedin applied position within the recess 12. Threaded through the upper edge of ,the' sill 1 is a jackscrew 16 having its lower end in contact with the upper face orwall of the bearing block 14 so that when 17 having the screw 16 is moved downwardly the forward end portion of the sill 1 will be elevated andvice verse, Each of the bearing blocks 14 serves as amounting for theforward axle operatively engaged with its op portions the'flanged wheel 18 ridposite en ing upon thetrackway T.

The beam 19 midway its length is provided with the forwardly directed arm 21 .fpivotally engaged as at 24 with a side silll. The oppositeend portion of the rock lever 23 is pivotally engaged, as at 25 with the piston rod 26 adapted to be reciprocated in any desired manner but preferably,

through themedium of air and in the same manner asemployed n the \Yestmghouse straight line'system, It is to be understood however that if preferred any type of brake mechanism may be employed which will suc-' cessfully meet the requirements of practice.

w At a predetermined point intermediate the side sills 1 the shaft 10 has fixed thereto a sprocket wheel 27 around which is directed the sprocket chain 28 also disposed around a sprocket wheel 29, fixed-tea snaftBO disposed transversely iofithetruck S, and rotatably supported by the'fside sills 1. .One end pore tion of the-shaft 30, outwardly of the adjacent sill 1, is.provided. with a gearwhee1 ,3l

for a purpose which willhereinafter be more particularly referred to; The loa ilfifg mechanism proper comprises a pair of forwardly and downw r ins:

elined side beams32 maintained in predetermined spaced relation by the;cross strips ,33. Depending from the side beams 82 adja-; cent the opposite ends thereof are the legs 34 provided at their-lower ends with the flanged wheels 35 riding upon the traekway A carried by the'supporting truck.

portions of the beams 32 are the transversely Rotatably supported at the opposite 'end.

disposed shafts 36.- Fixed tor each of the 7 an endless sprocket chain 38.":"Suitably enshafts 36; adjacent each end. thereof isa,- sprocket wheel 37 around which is disposed gaged with thechain 38am the buckets 39;.

It is believed-to b self-evidentthat' in prac-. tice, two chains 38 are employed,

extends downwardly and passes 'aroundthe sprocket wheel 41 carried by'the transversely The upper shaft .36 hascoperatively engaged therewith 'thej sprocket chain 40 which disposed shaft42 rotatably engaged with the.

longitudinally disposed horizontal sills 43.

The sills 43 are suitably sup-ported by the legs 34 adjacent "the lower endsthereof. Ata point substantially midway between the sills 43, the shaft 42 has fixed thereto a gear wheel 44 operatively engaged with the gear,

wheel 45 carried by tliedrivingshafts 46- of the engine E'which may beflof an, internal Y combustion type or of any other'type which will operate with 'convenienceand facility.

The engine E as herein disclosedfis sup-F ported on the transverse cross beam suit ably engaged with the beams 43 adjacentthe rear ends thereof.

The end portion I I from the "sprocket wheel 41 is provided; with of an; shaft i2 jirenot a second sprocket wheel 48 around which is' disposed a sprocket chain 49 which i'salso directed around a sprocket wheel 50 fixed to the shaft 51. The shaft 51 is r ot'atably sup ported by the forks 52 arranged at the lower end of the arm 53 depending from an .adja- 1 cent side beam'32 and as is particularly 'il-lustrated in Figs. 6 and 7 the sprocket wheel 50 is positioned between the forks '52.

he outer end portion "ofthe'shaft' 51 is provided with a pinion 54 which isadapted 'tojmesh with either the gear 55 or thegea r 56 rotatab'ly supported between the opposite end portions of the -spaced plates 57. The plates 57 are mounted for rockmg movement upon the shaft 58 rotatably supported by the forks 52 and the shaft 58 is provided at its inner. end with a beveled pinion 59 conshaft 58 has fixed. thereto a pinion 62 positioned between the plates 57. The gear 62 is constantly in mesh with the gear 56 and with an idle pinion 63. The pinion 63 is constantly in mesh with the gear 55.

' 55 or 56 to mesh with the gear 54 I provide.

the gears 55 and 56'are'in neutral position or free of th'e gear 54 the loading mechanism will'be maintained in a fixed positionupon the 'trackway'A but when it 'is desired to move the mechanism laterally of the sup porting truck S in either direction the gear 55 or. 56 will be caused to mesh with the gear 54. In order to impart the requisite rocking movement to the plates 57 to causethe gear one oi the plates 57 with the depending extension 64. 'Pivotally engaged with the extension 64 is-a rod 65 which extends rearwardly and has its rear end portion pivotally 'engaged'as at 66 with the lower end portion of the upstanding lever 67 pivotally mounted as at 6'8 with the outstanding platform 69 arranged at the inner end'portion of the adjacent sill 43. The lever 67 extends through a suitable opening 7 O'produced in the platform 69; The lever 67 is also provided with a latch mechanism 71 of a conventional type co-acting-with the upstanding rack 72 carriecl by the platform- 69.

- l'noperationthe upper stretch of each of i I .the chains 38 travels rearwardly so that the buckets 39 will be caused to properly engage the material M so that the same may be dischargedwithin the car 0 or other vehicle to be loaded and it will be self evident that the lower portion of the beams 32 may be raised "or lowered as the occasion may require through the medium of the jackscrew 16 hereinbefore referred to. Our improved machine is adapted for use within 1 mine or exteriorly thereof and when enterlng within a drift the rails 3 are separated as at 4 so that the extended portions of the trackway T will aliord no obstruction to the entrance of the apparatus. The shaft 42 has als fixed thereto a sprocket wheel 7 3 and around which is disposed at sprocket chain 74 which is also directed around a sprocket wheel -7 5 fixed to the transverse shaft 76 supported by the wheels 4&3 and preferably positioned directly below the cross beam 47. An end portion of the shaft 76 has fixed thereto a gear wheel 77 positioned between the plate 78 mounted for rocking movement upon the shaft- 76. The gear wheel 77 is constantly in mesh with a gear 79 andanidle gear 80. The gear 80 is constantly in mesh with the gear 81. The. gears 79, 80 and Slare rotatably supported by the plates 78 and porn tioned therebetween.
